I’ve been sharing slow cooker fudge recipes every few weeks for a few months now, starting with our simple chocolate fudge recipe and then easy slow cooker Christmas fudge. This Slow Cooker Peanut Butter fudge may well be my favourite so far. As a family we all love fudge and it’s something we love to make when friends and family are coming over or as a really lovely gift.

How easy is crockpot Peanut Butter Fudge to make?

This recipe took a few attempts to crack but I got there in the end. It’s worth pointing out that if you want a crumbly fudge rather than the softer slow cooker fudge we always create, put more peanut butter in and the same amount of extra chocolate. That turned out amazingly for any crumbly fudge fan but it was really hard to stir – and impossible to slice nicely!

Slow Cooker Peanut Butter Fudge

For this old fashioned peanut butter fudge recipe I used a mix of white and milk chocolate to give the fudge a peanutty colour. You can use just white chocolate to create peanut butter white chocolate fudge if you want to or you could create a chocolate peanut butter slow cooker fudge by using just milk chocolate.

We also used a smooth creamy peanut butter for this chocolate peanut butter fudge but I’m sure crunchy peanut butter would work well too. The peanuts we stirred in at the end were unsalted but if you’d like a salty kick to this delicious creamy peanut butter fudge you could use salted peanuts instead.

A lot of people add vanilla extract or vanilla essence to homemade fudge but we never have and it always tastes delicious so I don’t think it’s needed.

How long does slow cooker fudge keep for?

This slow cooker fudge keeps well in the fridge, in an airtight container for a couple of weeks. The flavour matures over the first couple of days of it being in the fridge so you get the full flavour after it’s been in the fridge for a few days.

Can you make this fudge in the microwave?

Many people make fudge in the microwave but I much prefer the control I have when I make it in the crock pot or slow cooker. If you don’t have a slow cooker, make it in the fudge by putting the ingredients in a microwave safe bowl and heating on short bursts in the microwave, stirring in between. Then follow the instructions as per the recipe below.

Can you make slow cooker fudge with evaporated milk?

Our slow cooker fudge works because condensed milk has a really high sugar content, needed to create that beautifully rich fudge. Evaporated milk isn’t the same, doesn’t have that sugar content and isn’t thick enough to help the fudge thicken and set. You can’t use evaporated milk in these recipes – so get some condensed milk instead.

Do you cook slow cooker fudge high or low temperature?

We always cook fudge on a high slow cooker temperature setting and it takes around 40 minutes in total. You could make it on the low setting but it would take longer and would still need to be stirred regularly. You may as well keep the slow cooker on high and be done in under an hour!

When cooking, is the slow cooker fudge lid on or off?

When making slow cooker fudge, you need to remove the slow cooker lid otherwise excess moisture would be retained in the slow cooker pot and the fudge wouldn’t thicken as it needs to.

If you’re looking for other fudge flavours to try making you can see all our previous recipes here. I have to recommend our cookies and cream fudge, Lotus Biscoff fudge and we have a vanilla fudge in the pipeline!

What equipment do you need to make slow cooker fudge?

Slow cooker fudge doesn’t need anything special to make it, and you probably already have everything you need at home, but this is the equipment we use:

Once you’ve got everything you need to make the fudge you can just keep making it again and again – in so many different flavours too!

  • I would never have thought of cooking fudge in the slow cooker. This looks really delicious, it’s a shame I’m the only one in the family that likes peanut butter…I may just have to make a batch for myself 🙂

  • This looks amazing and I have my first attempt in my slow cooker as we speak. So excited as chocolate and peanut butter are 2 of my favourite foods.
